Welcome

Periodic Table Graphics (PTG) is a taskforce of Wikipedia:WikiProject Elements (talk).
The taskforce aims to improve graphic and presentational aspects of the periodic table. It follows and shows scientific content.

Scope

[edit]
The graphics, not the scientific content.
By theme (topic), like categories, blocks, or by editorial form (like 18- or 32-column)

Goals

[edit]

Goals of the taskforce are to improve graphic presentation of the periodic table. This includes

Present scientific information appropriately and usefully. Considering Wikipedia is an encyclopedia.
Apply WP:ACCESSABILITY ('A11Y') guidelines, aims and principles.
Improve explanations, descriptions etc.

Tasks, Active

[edit]
State of Matter (SOM, Jan 2021)
  • Current 2020 SoM coloring (=use font colors) has issues.
As of 2021-01-23, an Emergency Edit has been made to make SoM-fontcolors into black all. W3C Contrast checking failed too often (5/18 existing combinations!)
A new presentation form (like icons not colors) is considered.
See Wikipedia talk:WikiProject Elements § Emergency edit: remove fontcoloring State-of-Matter, has wider discussion, interesting

Tasks, Future

[edit]
Micro PT (MICRO)
  • Could be redesigned to be more useful (like using larger cells).
Also, as used in {{Infobox element}}, can be made more effective.
Crystals
In {{Periodic table (by crystal structure)}}
The legend setup could be better. Why not use iconic images instead of colors? -DePiep (talk) 23:53, 23 January 2021 (UTC)[reply]
Metalloid graduals
These four classes better have gradual colors (say, blue-to-yellow in 4 steps).

Tasks, Past

[edit]
... – 2021-01
Category colors (CAT)
  • As of Jan 2021, this Taskforce PTG was buzy to find better category-colors.
Current live colorset is "2020" (as of 31 Dec 2020), see Wikipedia:WikiProject Elements/PTG/categories/2020 and {{Periodic table}}.
Moot as of Jan 17, 2021

Conventions

[edit]
  • In PTG, hex color triplets are shown in lowercase: 3af8ee.
  • "Chemical categorisation" explicitly refers to the science. For example, the "2020 categorisation" scientifically re-introduced "Halogens" category. After this, the topic "Colors of categories" will follow.
  • Category names are not relevant. For example, former PTM Post-transition metals is in 2020: OM Other Metals. Does not effect color design.
Also, exact category memberlist not very important. Except maybe when checking for neigbours (bordering).
